John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.
 
John is an English derivative of the Hebrew name Yochanan via the Latin name Iohannes, itself coming from the Greek Ioannes. John was a key name in early Christianity, borne by John the Baptist, John the Apostle and John the Evangelist, plus 84 saints and 23 popes, as well as kings and countless other illustrious notables. Contrary to popular belief, the names John and Jonathan are unrelated, the latter being an elaboration of Nathan.
 
Because many of today's baby Johns get their names for familial rather than stylistic reasons, John isn't as ubiquitous as it once was. For modern parents, the nickname Jack or an international form like Gianni feels much fresher. But John is still one of the Top 10 <a href="https://nameberry.com/search/boys-names/j">boy names starting with J</a> of all time.
 
The international versions of John are perennial classics in their own cultures: the French Jean, the Irish Sean, the Scottish Ian, the Welsh Evan and Ewan, the Italian Giovanni, and Gianni the Spanish Juan, the German Johann/Johannes, the Slavic Jan, the Russian Ivan, and on and on.
 
Celebrities who have gone with the timeless John include Michelle Pfeiffer, Bono, Johnny Depp, Lauryn Hill, Bridget Moynahan, and Rob Lowe.
 
Jon may be an abbreviated spelling of John or a short form of Jonathan.

Vivian, once an elderly lady name, is on the rise, along with all forms of <a href="https://nameberry.com/list/607/girls-names-that-mean-life">girl names that mean life</a> — from Zoe to Eva to those who share the vivid Viv syllable. It was one of the fastest-rising names of 2024, vaulting into the Top 100 in 2023.
 
The name is famous in legend and literature from Vivian, the enchantress of Merlin in the Arthurian romances, spelled Vivien in Tennyson's Idylls of the King. Originally, Vivian was the male form, Vivien the female: Vivien Leigh, for some reason, changed her name from Vivian. Melissa McCarthy and Ben Falcone have a daughter named Vivian, as do Gisele Bundchen and Tom Brady. A memorable movie Vivian was played by Julia Roberts in Pretty Woman.
 
Vivienne, the elaborated Gallic version, was chosen first by Rosie O'Donnell for her daughter and then catapulted to superstardom when Brad Pitt and Angelina Jolie used it for their twin daughter. This celebrity stamp of approval has given Vivienne a boost in popularity. An adult namesake is the British designer Vivienne Westwood.

Vincent is a name with a complex image. After being quietly used for centuries, it is suddenly seeming stylish, along wih other V names. Even the nickname Vince has been given a reprieve via actor Vince Vaughn and country singer Vince Gill. Vin Diesel was born with the more prosaic name Mark Vincent.
 Vincent was popular during the Middle Ages, especially among the French, who brought it to England. There are a number of St. Vincents, most famous of whom is St. Vincent de Paul, a seventeenth century French priest who organized societies of laymen to help the poor.
 Vincent has always been a favorite of Roman Catholic families, particularly in the Italian community. Its most notable bearer was Vincent van Gogh, but there also was philanthropist Vincent Astor, who gave it a patrician edge, and actors Vincent Price and Vincent D'Onofrio.
 Vincent/Vince/Vinny has appeared on screen as the central characters of My Cousin Vinny and Entourage. John Travolta had two key Vin-roles: Vinnie Barbarino in the TV series that launched him (Welcome Back, Kotter), and as Vincent Vega in Pulp Fiction. Vincent was the gentle giant on TV's Beauty and the Beast, and Ethan Hawke played a Vincent in Gattaca.

Matilda is a sweet vintage name that has been gently climbing the popularity list for the past 15 years, after a half-century slumber. The spunky children's book heroine Matilda is one factor in its rise, along with others of its class like Eloise and Caspian.

The comeback of Matilda, one of the most stylish girls' names starting with M, has been prompted by a boomlet of starbaby Matildas, beginning with chef Gordon Ramsey's in 2002 and Moon Unit Zappa's two years later. But the renaissance of this name of the charming Roald Dahl heroine was assured when Michelle Williams and the late Heath Ledger chose Matilda for their daughter. 
 Matilda was introduced to the English-speaking world by the eleventh century Matilda of Flanders, queen of William the Conqueror, then used for his granddaughter, known as Maud. In literature, Matilda appeared in Dickens's Nicholas Nickleby.
<p.>Trivia tidbit: The Matilda in the Australian song 'Waltzing Matilda' refers not to a person but to the knapsacks that swing, or waltz, on the backs of itinerant laborers as they walk along.
 Highly popular in England and Australia, Matilda has a choice of great nicknames: Tillie for the bold, Mattie for the shy, Tilda for the slightly more eccentric, such as Tilda Swinton, born Katherine Matilda.
 Molly Ringwald used the spelling Mathilda for her daughter.
